Njengemveliso yerabha yesitywina yesiko, umsesane wokutywina werabha kufuneka ube ne-elasticity elungileyo, amandla, ukuxhathisa okuphezulu, ukomelela kunye nobude ngexesha lekhefu.Ezi zalathisi zineemfuno eziphezulu kwaye zingasetyenziselwa ukuvelisa amatywina erabha asebenza kwiindawo ezingenawo i-oyile nezingadlekiyo ukusuka ku-20°C ukuya kwi-100°C.Phakathi kwabo, ukuchasana kokugqoka kuchaphazela ngokuthe ngqo ubomi benkonzo yendandatho yokutywina kunye nomphumo wokutywinwa.Ke ungaphucula njani ngakumbi ukuxhathisa ukunxitywa kweringi yokutywina yerabha kwimveliso eyiyo?
1. Ukwandisa ngokufanelekileyo ubulukhuni berabha
Ngokwethiyori, ukonyusa ubulukhuni berabha kunokonyusa ukuxhathisa kwerabha kwi-deformation.Umsesane wokutywina werabha kunye nomphezulu woqhagamshelwano unokudityaniswa ngokulinganayo phantsi kwesenzo soxinzelelo, ngaloo ndlela kuphuculwe ukuxhatshazwa kokugqoka.Ngokuqhelekileyo, abaninzi abavelisi beringi yokutywina irabha badla ngokunyusa umxholo wesulfure okanye bongeze inani elithile learhente yamandla ukuphucula ubulukhuni berabha.
Kufuneka kuqatshelwe ukuba ubulukhuni bendandatho yokutywina irabha akufanele ibe phezulu kakhulu, ngaphandle koko kuya kuchaphazela i-elasticity kunye ne-cushioning effect ye-ring yokutywina, kwaye ekugqibeleni iholele ekunciphiseni ukuxhatshazwa kokugqoka.
2. Lungisa i-elasticity yerabha
Ukuze kuncitshiswe iindleko zeemveliso zerabha, abavelisi beemveliso zerabha baya kuzalisa inani elikhulu lokuzalisa irabha, kodwa i-rubber eninzi kakhulu iya kunciphisa i-elasticity yerabha.Kuyimfuneko ukulawula idosi ngokufanelekileyo, ukwandisa ngokufanelekileyo i-elasticity yerabha, ukunciphisa i-viscosity kunye ne-hysteresis ye-rubber, kunye nokunciphisa i-coefficient of friction ukuze kuphuculwe ukuxhathisa ukunxiba kwezitywina zerabha.
3. Lungisa iqondo le-vulcanization
Ngokweempawu zokusebenza kwe-rubber vulcanization, abavelisi beemveliso zerabha bahlengahlengisa ngokufanelekileyo inkqubo ye-vulcanization kunye neeparamitha ze-vulcanization zamatywina erabha ukunyusa izinga le-vulcanization kunye nokuphucula ukuxhathisa ukunxiba kwetywina lerabha.
4. Ukuphucula amandla okuqina erabha
Xa i-rubber isetyenziselwa ukwenza amakhonkco okutywinwa kwerabha, ukusetyenziswa kweefayili zerubha ze-particle emihle ekuqulunqweni kunokunyusa amandla e-intermolecular ngokuphucula amandla okunyamezela kunye noxinzelelo lwe-rubber, kwaye kwinqanaba elithile liphucula ukuxhatshazwa kwerubha.
5. Nciphisa i-coefficient ye-friction surface yeringi yokutywina irabha
Ukongeza izinto ezifana ne-molybdenum disulfide kunye nenani elincinci legraphite kwifomyula yeringi yokutywinwa kwerabha kunokunciphisa i-coefficient ye-friction surface yeringi yokutywinwa kwerabha kunye nokuphucula ukunyanzeliswa komsesane wokutywina.Xa abavelisi bemveliso yerabha basebenzisa irabha ukwenza irabha yokutywina irabha, banokusebenzisa irabha ehlaziyiweyo ukuze banciphise ixabiso lempahla ekrwada yeemveliso zerabha kwaye bagweme ingxaki yamandla omatshini kunye nokumelana nokunxiba kwerabha okubangelwa zizigcwali zerubha ezigqithisileyo.Uyilo olunengqiqo lwe-rubber yokutywina ifomyula yokutywina, ukulungiswa okufanelekileyo kweeparamitha zenkqubo ye-vulcanization, kunye nokukhethwa kwezinto ezifanelekileyo zerabha zerubha azikwazi ukunciphisa kuphela iindleko ze-rubber yokutywinwa kwezinto eziluhlaza, kodwa nokuphucula ukuxhathisa ukunxiba kwamakhonkco okutywina irabha.
